UNITED STATES PATENT EEICE,

LEOPOLD FRITZ, OF MILWAUKEE, IVISOONSIN.

CAR-JACK.

SPECIFICATION forming part of Letters Patent No. 582,468, dated May 1 1,1897.

Application filed March 10, 1897.

To all whom it may concern:

Be it known that I, LEOPOLD FRITZ, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inOar-Jacks; and I do hereby declare that the following is a full, clear,and exact descriptionthereof.

My invention relates especially to devices for replacing railway-carsupon their tracks when they have accidentally left the same; and itconsists in certain peculiarities of construction and combination ofparts, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is avertical central sectional View of mydevice, showing its mode of operation. Fig. 2 is a partly-sectional planview, and Fig. 3 is a transverse vertical sectional view of a portionthereof.

Referring to the drawings, A represents the movable platform of mydevice, whichis intended to be placed adjacent to the end of the car tobe moved. This platform consists, preferably, of a solid center a,(which may be of wood,) framed with cross-beams b b, secured together bybolts 0 c and cross-ties (Z (Z, and there being preferably additionalcrossties e 6 between the projecting ends of the cross-beams, wherebythe platform may be drawn or moved about to the desired points by thehook B. The upper face of the solid center a is,provided with recesses ff for the reception of series of antifriction-rollers g g. It is obviousthat the platform may be cast or otherwise formed in whole or in part ofmetal, but the construction described is the preferable one.

C is a horizontal revolving disk formed, preferably, of wood, but, if ofwood, with a metallic base h, and having, preferably, a metallic band orperiphery 1 D is a standard rising from the center of said disk, theupper part of said standard being divided, as shown at j 7'.

E is a pivot pin extending downward through a vertical opening in thelower part of the standard D and projecting into a socket 7;; in thecenter of the platform A, said pin E having aneye in its head throughwhich a bolt m passes, whereby the said pin E is rigidly secured to thestandard D.

Serial No. 626,768. (No model.)

If the standard D is made of wood, the outer sides of its upperportionsjj are preferably reinforced'by metallic facing-plates not, asshown, and said partsj j are provided with registering series of holes 00. Straps or stayrods 19 p are provided, running from the disk 0 to thesaid standard, to brace and strengthen the latter.

F is the operative lever of my device, and is made, preferably, of metalwith a socketed shank to receiveawooden handle-bar G. This lever isprovided with a series of holes q q, and said lever is slipped downbetween the parts jj of the standard D and adj nstably secured thereinby a pin H, passing through one of said holes q and opposed holes 0 0 inthe standard.

I is a clip to prevent the divided parts jj of the standard fromspreading in use when under strain, the upper ends of said partsjj beingnotched or recessed for the reception of the horizontal part of saidclip, and the latter being preferably attached to the'standard in anysuitable way, as by hinge-bolt r, to prevent its loss in transportation.The standard D is further preferably strengthened by a band-clip t, asshown.

The forward end of the lever F has swiveled thereto a bearing-plate J,(with washers, if desired, on its pivot-pin, as shown,) the uppersurface of said plate being preferably grooved or roughened to increaseits hold.

K is a chain secured to the lever F back of the standard D, and L is ahook on the disk 0 for engagement with any of the links of said chainwhen it' is desired to prevent the forward end of the lever from beingforced downward in use by the weight upon it.

The forward end of the lever F is preferably formed with a downwardcurve or bend, as shown at u, just back of the bearingplate, to providespace for any downward projections on the end of the car.

The operation of my device will be readily understood from the foregoingdescription of its construction, taken in connection with theaccompanying drawings, Suppose that a street-car, for example, is oif.the track. My device is brought to a point near the end of the car to beoperated upon, the hook B-being used to secure the exact positionrequired. The lever is introduced under the car with the bearingplate Jjust beneath the rear end of the ear M and the handle-bar of, the leverdepressed. Then by turning the said lever to one side or the other thecar can be readily moved until its wheels are just over the tracks. Ifit becomes necessary to get beneath the car afterit has been raised thelever is made stationary by means of the described chain K and hook L,and thus all danger is obviated. \Vith my device the replacement of acar upon its track is usually a matter of only a few minutes, whereaswithout such a device frequently a very long time is required.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a car-jack, the combination of a platform or base, a rotary diskpivotally secured thereon, a standard rising from said disk, and a leverad j ustably secured to said standard, and having a bearing-plate at itsforward end, substantially as and for the purpose set forth.

2. In a car-jack, the combination of a platform or base, provided Withseries of antifriction-rollers on its upper surface, a rotary diskpivotally secured to said base and resting 011 said rollers, a dividedstandard rigidly secured to and rising from said base and provided withseries of adjusting-holes, a lever also provided with a series of ad]usting-holes,

supported between the divided portions of the standard, a fulcrum-pinfor adj ustably securing said lever in position, and a bearing-plateswiveled on the forward end of saidlever, substantially as set forth.

3. I11 a car-jack, the combination of a platform or base, provided withseries of antifrietion-rollers on its upper surface, a rotary diskpivotally secured to said base and resting on said rollers, a dividedstandard rigidly secured to and rising from said base, and provided withseries of adjustingdioles, a lever also provided with a series ofadjusting-holes supported between thedivided portions of the standard, afulcrum -pin for ad justably securing said lever in position, abearing-plate swiveled on the forward end of said lever, a chaindepending from the lever back of the standard, and a hook for engagementwith any of the links of said chain, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of \Viscousin, in thepresence of two witnesses.

LEOPOLD FRITZ.
